Diminishing returns along the border

Arrests of people crossing the border with Mexico have fallen to historic lows. The Washington Post reported on Saturday

The Border Patrol apprehended 327,577 illegal crossers along the U.S.-Mexico border in fiscal year 2011, which ended Sept. 30, numbers not seen since Richard Nixon was president, and a precipitous drop from the peak in 2000, when 1.6 million unauthorized migrants were caught. More than 90 percent of the migrants apprehended on the southwest border are Mexican.

...“We have reached the point where the balance between Mexicans moving to the United States and those returning to Mexico is essentially zero,” said Jeffrey Passel, a senior demographer at the Pew Hispanic Center, whose conclusion was shared by many migration experts.

Yet the Obama administration continues to deploy 1,200 National Guard troops along the border, mostly for show.

President Obama’s decision last year to send 1,200 National Guard troops to the U.S.-Mexico border may have been smart politics, but a growing number of skeptics say the deployment is an expensive and inefficient mission that has made little difference in homeland security

The rules of engagement, rightly, limit the role of the National Guard to observation. The net effect, however, is that the troops increase the cost of securing the border by about $110 million per year but have little impact on security itself. The Post story continues

In an August report on the costs and benefits of an increased role for the Defense Department along the U.S.-Mexico border, the Government Accountability Office told Congress that it takes three people to do the job of one: two Guard soldiers to spot an illegal crosser and one federal agent to catch him.

Since 9/11, the United States has greatly strengthened its fence along the border. It has also doubled the number of Border Patrol agents, with predictable effects on border crossings and apprehensions.

At a time when the military is already strained and where the government is looking to save every penny that it can, an ineffective $110 million National Guard "troop surge" along the border seems especially wasteful and a bad return on investment. President Obama should end the deployment at the end of this year and allow the troops to return to their home states and bases.
